Everything I brew--beer, wine, cider--I bottle. I don't go through it fast enough to warrant kegging.
Any tips/tricks to successful kegging? ie) how important is it to start with full keg, recommended PSI, etc. Thx & Cheers!I only keg for the simple reason that it's easier and less time consuming. Especially since my friends and family like it sweet as I do. When I travel I pour off a growler. I also used sanke style kegs because I found them cheap and already had some sanke style kegorator parts left over from my macro- brew days.
Bottles are great to drink out of, but since we host a few large parties every year, kegs have been a much better choice for me.
You can never vent all the O2 from a keg headspace because each time you pressurize/vent you will remove at best only 50% of the oxygen. I've read of tests where purging headspace 4-5 times did not fully remove oxygen; it is a futile endeavor.
There are charts for that - number of purges vs pressure. I'm sure I've seen them in the beer kegging forum here. 10 purges at 30 psi gets you to like .01% oxygen (IIRC).
OK, sure, you can get close (but never actually zero) to purging out all the O2 with enough purges, but at a certain point it becomes a huge waste of CO2 and time.
Assuming constant temperature, you will use 30X more volume of CO2 to purge a 1/2 keg with 30 psi ten times versus pushing out a full keg of starsan at 3 psi. That's a huge difference. (pV=nRT; simplified to n=pV)
.
It would be more effective to just use CO2 to push starsan out of a keg as chevalcider showed in the video above, then fill with cider and know that your keg is 100% purged.
